MAC 1105 Module Test 2 Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. You are given a table showing input and output values for a given function y 1 = f(x). Use the table to answer the question. 1) What is the x - intercept of the graph of y = f(x)? A) - 2 B) 6 C) - 1 D) 0 Solve the formula for the specified variable. 2) I = nE nr + R for n A) n = IR Ir + E B) n = - R Ir - E C) n = IR(Ir - E) D) n = - IR Ir - E A linear function y 1 has been graphed in an appropriate viewing window. Use the x - intercept method to solve the equation y 1 = 0. 3) A) 4 B) 5 C) 2 D) 0 Solve the formula for the specified variable. 4) P = a + b + c for a Solve the problem. 5) The temperature of water in a certain lake on a day in October can be determined by using the model y = 15.2 - 0.537x where x is the number of feet down from the surface of the lake and y is the Celsius temperature of the water at that depth. Based on this model, how deep in the lake is the water 11 degrees? (Round to the nearest foot.) 1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
